Question #680375 on Yade changed: https://answers.launchpad.net/yade/+question/680375 Status: Answered => Open zheng is still having a problem: Thanks Caulk and Jan, this solved most of my question. However, deleting particles by sizes may not be suitable for all cases. For example, how to delete 10% of particles by number if I only have one particle size? This time the "percentile(a,q)” may not work. Could you please give me any clues? Thanks so much.

[Yade-users] [Question #680375]: How to delete 10% percent of small particles?
New question #680375 on Yade: https://answers.launchpad.net/yade/+question/680375 Dear all, I am very new in Yade. In my simulation, I have a polydisperse particle size distribution, from size 0.2~1.0mm. Thanks to this poster: https://answers.launchpad.net/yade/+question/211937, I now know how to delete all particles with a certain diameter or position. Now I need to delete 10% of the smallest particles (d=0.2mm) every 100 steps, but I cannot figure out how to realize this function? Could anyone please give me any clues? Thanks so much!
